Land art and site specific sculpture - land art uses
the environment and its scale as its material. Concrete art is expressed in
material itself with which the artist introduces her non-representational objective.
Public art can be viewed and accessed by observers.

revisited (Lucien den Arend)

The red, black and white walls superimposed on each other.

Like the screens on a stage, the colored walls compose and delimit the setting
of the urban oasis.
The black (actually dark gray) wall on the right divides the main area of the
site specific environment from the street - or rather, bicycle route.
